Glossary term Bandwidth The frequency range over which a signal, channel, instrument, or control system can transmit or respond with acceptable performance. Glossary term Jitter Short-term timing variation of signal edges, samples, packets, or clock events from their ideal positions. Glossary term Noise Figure A receiver or component metric describing how much internal noise degrades signal-to-noise ratio. Glossary term Optical Fiber A dielectric waveguide that transmits light for communication, sensing, or power delivery. Glossary term Sampling Theorem The principle that a band-limited signal can be reconstructed from samples taken above twice its highest frequency. Glossary term Signal-to-Noise Ratio A signal-quality metric comparing desired signal power with noise power over a specified bandwidth and measurement condition. Glossary term Uplink Budget A link budget for the transmission path from a ground or user terminal to a satellite or network node. Glossary term Waveguide A physical structure that confines and guides electromagnetic, optical, microwave, or acoustic waves along a defined path. Glossary term X-Band Radar A radar system operating in the X-band microwave range, commonly used when compact antennas and fine angular resolution are important. Glossary term Yagi-Uda Antenna A directional antenna using one driven element and parasitic reflector and director elements.
